Substitute Part Grouping Explanation

Substitution of the AD650KN is determined by strict equivalence across the following critical parameters:

• Functional Type: Volt to Frequency and Frequency to Volt Converter
• Maximum Frequency: 1 MHz operation
• Linearity Specification: ±0.1%
• Temperature Coefficient: ±150ppm/°C
• Package Configuration: 14-DIP (0.300", 7.62mm) through-hole
• Manufacturer: Analog Devices Inc.
• Base Product Number: AD650

The AD650KNZ qualifies as a direct substitute because it maintains identical electrical specifications and package configuration while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations
